SINGLE-TRIGGER DOUBLE-BARREL GUN.

' SPECIFICATION formingpart of Letters Patent N 0. 665,634, dated January 8, 1901. Application filed July 11, 1900- Serisl No. 23,202- (No model.)

trigger, the arrangement being such that the,

trigger mechanism is automatically shifted for the discharge of the barrels insuccession.

The nature of the construction and operations of this invention will fully appear from the subjoincd description, when considei'edin connection with the accompanyingdrawings,

3 in which Figure 1 is a side elevation of a portion of a gun-stock having one look removed and a portion of the central part of the stock broken away to show the relative position of my invention and its adaptation for cooperation with the hammers of the locks. Fig. 2 is a perspective view of my new single-trigger mechanism, together with the lock, showing its adaptation for lifting the sear and the relative position of the safety guide-pin in connection therewith. Fig. 3 is a vertical section through the gun-stock, the locks, and the trigger-plate on line 3 3 on Fig. 2 looking in direction of arrow 1. Fig. 4 is alike vertical section through the stock on line 4 4 looking in direction of arrow 2. Fig. 5 is a vertical section through the lock-plate, the triggersupporting block, and the studs on line 5 5, Fig. 1. Fig. 6 is a top or plan view of my new trigger mechanism.

A, Fig. 1, represents a portion of a gunstock. B is a cavity in its side occupied by one of the gun-locks, and C is the triggerguard. In the stock from the under side I make acavity or chamber Between the two lock-cavities to receive the operating parts of my new trigger mechanism. D is a recessed or hollow block firmly attached to the trigger-plate E, and F is the trigger occupying a slot in said plate and has a bifurcated upright arm f, by which it is pivoted at f in the upper rear corner of said block D. g is a spring fixed invthe trigger-plate, with one end bearing against said arm f for holding the trigger in its normal position. II is arear arm of the trigger occupying the slot in the trigger-plate E. G is a lever occupying the space in the bifurcated arm f andis loosely held in place by the pivotf. arm II of the trigger, its forward end ex- Its rear end rests upon the tends to the front line of the block D, and its uppercorner is cut away, so as to. pass under the'screw-tapped cross-piece of the block D. (Seen atD in drawings.) The rear end of the lever G is made to shift from side to side on the pivot for the purpose of changing its position from under one soar to the other of the locks, respectively, by means as follows: I and J are hollow studs fixed in the sides of the block D, in which-are provided telescoping pins 'ij',

the inner heads of which bear, respectively,

against the sides-of the forward part of the said lever G. The studs extend laterally through the side walls of the middle cavity into the side cavities, so that the outer heads ofsaid pins ij bear, respectively, against the tumblers 7c of the hammers. The pins 'ij inside the studs are surrounded by spiral springs s s, (seen in Fig. 6,) which bear against the pin-heads to force them outwardly and inwardly, respectively. of the springs is greater than the other, the purpose ofwhich is to hold the tail of the lever G to one side, as seen in Fig. 3, under the sear of the look at one side ofthe gun. The operation of this. device is as follows; When The tension of one both locks of the gun are'cocked, thepins are contacted, respectively, with the tumblers 70 k, the spring on one pin being stronger than the other. The tail of the lever G is still held to one side, as seen at H, in drawings. Now when the trigger is pulled the tail of the lever G is raised by the arm H of the trigger and the sear of the lock on that side of the gun is lifted and the barrel discharged. This also releases the pressure of the tumbler of that hammer on the pin 41. Then the pressure of the spring on the opposite pin j, which is greater than that on the pin '5, forces the head of lever G over and shifts the tail of said lever over to the right. This brings the tail of the lever under the sear of the opposite hammer. Now by again pulling on the'trigger the other barrel is discharged, and thus the two barrels are discharged in rapid succession by two pulls on the one trigger. This description "pertains to discharging the lefthand barrel first. In order to reverse this order'to discharge the right-hand barrel first, I provide as follows:

P is a push-pin fixed in a hole in the guard and trigger-plate, which'is to be pushed up for its upper end to pass between the front end of the lever G and the side of the block D. This will holdthe tail of the lever over to the right and under the sear of the hammer on the right side of the gun. A spring V is fixed on the triggerplate, one end of which will beat-against the pin when up to hold it in place. Now when the trigger is pulled the right hand barrel is discharged first. The push-pin is pushed down by the movement of the lever and the spring-pin i will force the front end of the lever over to the right and bring the tail under the sear of the other hammer. Then by the second pull on the trigger the barrel on the left is discharged.

T is a safety guide-pin fixed in the stock, with its lower end reaching down between the ends of the two sears. (Seen inlgigs. 2 and 4.) The end .of lever G shifts under this pin and the sears: This pin serves to guide the upward movement of the lever and prevent its contacting with both sears at the same time.

W is a weight pivotally attached to the le-' -ver G,. with its lower end restingupon the trigger-plate. Its purpose is to hold the lever steady and prevent jarring by the recoil of the gun. I

Having described my invention, what I claim is 1. In adonble-barrel shotgun provided with two locks and but one "trigger, a rear arm H on said trigger, a block supported on the trigger-plate and having, the trigger pivotally supported therein, a lever G loosely supported on the trigger-pivot with its rear end-lying on the rear arm H of the trigger, hollow studs I J attached to the sides, respectively, of said block, and extending laterally through to the lock-chambers, spring-actuated pins 'ij contained in said studs and contacting, respectively, with the tumblers 7;- 7cof the two locks, the spring in one stud having greatertension than the other, whereby said lever is made shift-able, substantially as and for the purpose set forth.

2. The combinatiomin a. double-barrel shotgun, having two locks and but one trigger, a rear arm [I on said trigger, of the block D mounted on the trigger-plate, and having-the trigger pivotally supported thereby, the lever G loosely supported on the trigger-pivot, with its rear end lying on the rear arm II of the trigger, thehollow studs I J attached to the sides, respectively, of said block, and extending laterally through to the lock-chambers, spring-actuated pins 1' contained in said studs, and contacting, respectively, with the tumblers I: k of the two locks, and the safety guide-pin '1 fixed in the stock, and adapted to guide the lever fol-discharging the barrels separately, substantially as described.

3. The conibination,inadouble-barrel shot-. gun, having twolocks and butone trigger, a rear arm H on said trigger, of the block D mounted on thetrigger-plate, and having the trigger pivotally sn pported'thereb y, the lever G loosely supported on the trigger-pivot, with its rear end lying on the rear arm Hof the trigger, the hollow studs I J attached to the CHARLES EDWARD GOODWIN.
